LOCOMOTIVE CRANE.

APPLICATION FILED MAY I3. 19,16.

Y a citizen of the United States,

-Applicationfllcd May 13, 1916. Serial No. 97,265.

- in handling heavy materials at the sides of a railway track withinpreach of the crane hook on the hauling line or hoistlng rope of the4crane.

9* The lifting capacity andthe range of lift"4 mg movement of locomotivecranes as con- .1 i clearances necessary -on standard railroads,

structed heretofore, are materially limited, owing to the restrictionsimposed by the the distance between tracks the headl clearance orheightof the machine and curves in the tracks all being limitingfactors.

One object of my invention is to provide v novel' means whereby thelifting capacity of p locomotive cranes is materially increasedwithoutincrease in thehead room orclearancemecessary in transporting thecranes from place to place on existing railways.

Another obj ect of this invention is to provide novel means whereby alocomotive crane is adapted for the u'ses of aderrick car, whileretaining the characteristics of the locomotive crane as to head room'or clearances required in transferring the apparatus after, and to bespecifically pointed out in the appended claims.

, lift from place to place on railways, and as to mg capacity ofi to oneside.

further object of the invention is to provide a locomotive crane ofimproved construction having novel means whereby the lifting range andcapacity f the crane are quickly increased in the field, or in anyparticular location wherein it is desired to employ the crane inhandling materials.

A still further object of my invention is the provision upon existing aswell as new locomotive cranes and arrangement of parts shown in thedrawings, tobe more fully'described herein.-

my invention. Fig. 2 is a sectional"'eleva-.I

back stays forming part of my improved crane.

'In the accompanying drawings, the numeral 2 designates the body of alocomotive crane having track wheels 3. by which the crane is mounted onthe track rails 4 of a railway and on the' ends of the body 2 arestandard car couplers 5 by which the loco- Amotive crane may bedetachably connected l1n a tralnof rallway cars,

when being hauled from place to place.

Secured on top of the body 2 is a base 6 forming a circular track onwhich the main frame 7 of the crane is rotatably mounted. Pivotallyconnected at its lower end, by a pivot pin 8, to the main frame 7, andarranged to swing vertically relative thereto, is a boom or arm 9. Alsomounted on the frame 7 to rotate therewith on the body 2 is the usualcrane operating mechanism comprising winding drums, a druml drivingmotor or motors and, when steam is employed as the motive force, as withthe apparatus illustrated, a steam boiler. The cabin 10 also mounted onthe main frame forms a housing or shelter for the crane drivingmechanism and crane operator. Connected at its lower end by pins l1, tothe sides 12v of the main frame 7 is an articulated A frame 90 ig. 1.Fig. 3

ward to a connection with a winding drum formmg part of the craneoperating mechanism. The hauling line 22 of the crane load connected atone end to a winding drum of the crane mechanism passes over the sheave23 on 'the upperend -of the boom `9 and extends downwardly to the hookor pendant block of the load fall.

Attached to the rear end of the body 2 of the crane by automaticcouplers 5 isla'ten-uby which it .y

der car 23 having wheels'gA; mounted on the track rails f counterweightwhich may conveniently be a y and positioned on the rear end of thistender carl23 is a.;

'ropes forming the back stays 27 are provided with eyes by which theback stays are connected to the turnbuckles 31 at the lower endsthereof. The turnbuckles 31 are pivoted to brackets 32 which are securedto the sides of the tender car 23 at the rear end thereof.

In using the crane the parts are assembled as shown and on account ofthe counterweighted tender car 23 and the back stays 27 connecting the Aframe13 to the rear end ofthe tender car 23 for lifting a load directly,or nearly directly ahead or in front of itself a longer boom 9 can beused for the same load thus increasing the'reach or radius of action ora heavier load can be lifted -with the same length of boom, while thelifting capacity of the crane to one side is not materially altered.

When extended as shown in drawings the boom 9 will have an operativeswinging movement from alongside one side of the back stays 27 aroundthe front of the crane body 2 to a similar position onthe opposite sideofthe tender car.

The apparatus is operated in the same manner as with the 'ordinarylocomotive `crane, and, when found necessary or desirable, side guyswill be provided on the A frame to extend to dead men or other suitableanchorage erected on opposite sides of the railway tracks, adjacent tothe position in which the locomotive crane is placed for use, in loadingand unloading cars and in lifting materials from one side of the trackto the other at a distance materially greater from the crane thanwithout the side guys.

When transporting the crane from place to place the A frame 13 can beuncoupled from the main frame 7 and the stiff legs 14 and with the backstays 27 .packed wlthin the tender car. The stiff legs 14 allowed todrop onto the top of the cabin 10 or on tol counterweight 25 on the rearend ofthe The advantages of my invention will be tender car or the boom9 can be disconnected from the frame 7 and with topping lift 15--18packed in the tender car, thus enabling the crane and tender car to'betrans'- ported on railroads havmg'the usual clearances.

loads immediately in front or'ahead of the crane; or the boom may belengthened considerably so as to increase the reach or distance ahead orin front of the cr'ane at which a load may be lifted. The apparatus issimple and Will not require frequent repairs.

Modifications in the construction and arrangement of the parts may bemade within the scope of my invention as dened in the appended claims.

. I claim t- 1. In a locomotive crane, the combination of a .wheeledcrane body having a horizontally rotating main frame, a verticallyswinging boom pivoted at one end to the main frame, an A frame havingits lower end pivotally connected to said main frame, stiff legsconnecting the upper end of said A .frame and the main frame, af loadfall on the boom, a topping lift hoist donnecting the upper end of theboom to the A frame, a tender car coupled to the crane. body, a

counterweight at one end of said tender car,

main frame, an A frame pivotally connected to said main frame, a loadfall on the boom, a topping lift hoist connecting the upper end of theboom to the A frame, a tender car coupled to the crane body, acounterwelght at one end of said tender car, and adjustable back staysconnecting the upper end of said A frame with the counterweighted endofthe tender car. j j
